1. An electric charging controller, comprising: circuitry configured to store, in a memory of the electric charging controller, a plurality of IDs of a plurality of external devices, each ID of the plurality of IDs uniquely identifying each external device of the plurality of external devices; receive, from an external device of the plurality of external devices, an ID of the external device; determine whether the received ID of the external device is stored in the memory; control charging of the external device from a power server that receives power from a non-power-grid source in a case where it is determined that the received ID of the external device is stored in the memory; inquire of an external server about the received ID in a case where it is determined that the received ID of the external device is not stored in the memory; and transmit information of a charging amount of electric power.

2. The electric charging controller of claim 1 , wherein the circuitry is further configured to: receive, from the external server, information of the received ID in response to inquiring of the external server about the received ID.

3. The electric charging controller of claim 2 , wherein the circuitry is further configured to control charging of the external device from the power server in a case where the information of the received ID is received from the external server.

4. The electric charging controller of claim 2 , wherein the circuitry is further configured to store, in the memory, the information of the received ID received from the external server.

5. The electric charging controller of claim 1 , wherein the circuitry is further configured to control charging of the external device from the power server in a format compatible with the external device based on the received ID of the external device.

6. The electric charging controller of claim 1 , wherein the non-power grid source is configured to transmit electric power independently from a power grid source.

7. The electric charging controller of claim 1 , wherein the external devices are electric vehicles.

8. The electric charging controller of claim 1 , wherein the circuitry is further configured to calculate an amount of tax to be applied for an amount of electricity used from both a power grid and the non-power-grid source in charging of the external device based on a registration location of the electric device.

9. The electric charging controller of claim 8 , wherein the circuitry is further configured to associate the calculated amount of tax to the external device.

10. The electric charging controller of claim 9 , wherein the circuitry is further configured to calculate the amount of tax by including at least one of a state tax rate and a local tax rate according to the registration location.

11. The electric charging controller of claim 8 , wherein the circuitry is further configured to calculate the amount of tax by including in the calculation at least one of a charging time, and a battery model.

12. The electric charging controller of claim 8 , wherein the circuitry is further configured to apply a tax credit as part of calculating said amount of tax, the tax credit corresponding to an incentive offered by a taxing authority.

13. The electric charging controller of claim 12 , wherein the incentives include incentives for using power supplied from a private electric power source, the private electric power source being an organic source disconnected from an existing commercial power grid.

14. The electric charging controller of claim 8 , wherein the external devices are electric vehicles, and the circuitry is further configured to: receive a recorded driving history of the external device; and calculate an apportionment of the amount of tax according to different taxing jurisdictions included in the recorded driving history.

15. The electric charging controller of claim 14 , wherein the recorded driving history indicates one or more roads on which the electric vehicle has driven, and the circuitry is further configured to calculate the amount of tax based on the one or more roads indicated in the recorded driving history.

16. The electric charging controller of claim 14 , wherein the circuitry is further configured to: determine, based on the recorded driving history, a new charging area where said electric vehicle will travel following charging; and calculate the apportionment of said amount of tax according to different taxing jurisdictions included in said new charging area and said recorded driving history.

17. The electric charging controller of claim 8 , wherein the registration location identifies a location where the external device is registered for tax purposes.

18. A method for controlling electric charging, the method comprising: storing, in a memory, a plurality of IDs of a plurality of external devices, each ID of the plurality of IDs uniquely identifying each external device of the plurality of external devices; receiving, from an external device of the plurality of external devices, an ID of the external device; determining, using circuitry, whether the received ID of the external device is stored in the memory; controlling charging of the external device from a power server that receives power from a non-power-grid source in a case where it is determined that the received ID of the external device is stored in the memory; inquiring of an external server about the received ID in a case where it is determined that the received ID of the external device is not stored in the memory; and transmitting information of a charging amount of electric power.

19. A non-transitory computer readable medium including executable instructions, which when executed by a computer cause the computer to execute a method for controlling electric charging, the method comprising: storing, in a memory, a plurality of IDs of a plurality of external devices, each ID of the plurality of IDs uniquely identifying each external device of the plurality of external devices; receiving, from an external device of the plurality of external devices, an ID of the external device; determining whether the received ID of the external device is stored in the memory; controlling charging of the external device from a power server that receives power from a non-power-grid source in a case where it is determined that the received ID of the external device is stored in the memory; inquiring of an external server about the received ID in a case where it is determined that the received ID of the external device is not stored in the memory; and transmitting information of a charging amount of electric power.
